Abstract
A method for forming a liquid crystal display device, which includes steps of forming a metal film over a substrate, patterning the metal film to form a first gate electrode and a first capacitor electrode as a part of a first capacity element, and forming a first insulating film over the metal film. The steps further include forming a first polycrystalline-silicon layer over the first insulating film, and patterning the first polycrystalline-silicon layer to form a second capacitor electrode as a part of the first capacity element and a second capacity element, while additionally including the steps forming a second insulating film over the polycrystalline-silicon layer, forming a second polycrystalline-silicon layer over the second insulating film, and patterning the second polycrystalline-silicon layer to form a second gate electrode and a third capacitor electrode as part of the second capacity element.
